Benzyl 1-[({2,5-difluoro-4-[(2-{[(3-hydroxyazetidin-1-yl)carbonyl]amino}pyridin-4-yl)oxy]phenyl}amino)carbonyl]cyclopropanecarboxylate (84.2 mg) was dissolved in tetrahydrofuran and methanol (1:1) (2 ml) under a nitrogen atmosphere. 10% palladium on carbon (33.2 mg) was added and the air in the reaction vessel was replaced by hydrogen, and the mixture was stirred at room temperature for 20 hours. The air in the reaction vessel was replaced by nitrogen, and triethylamine (0.0435 ml) was added, and the mixture was stirred for 30 minutes. The catalyst was removed by filtration, and washed with methanol. The filtrate was concentrated under reduced pressure to give the title compound (75.3 mg, 88%) as a white solid.
